목 적: 본 연구의 목적은 폐쇄성수면무호흡증으로 하악 전방이동장치 치료를 시행한 환자들에게 하악전방이동장치의 유용성을 확인하고, 하악전방이동창치 치료시 하악의 전방이동량이 미치는 영향을 평가하고자 하였다. 방 법: 2007년 1월부터 2009년 2월까지 코골이 및 수면무호흡을 주소로 분당서울대학교병원에 내원하여 야간수면다원검사를 통해 폐쇄성수면무호흡증으로 진단받은 환자 중에서, 치료법으로 하악전방이동장치를 선택한 총 86명의 환자를 후향적으로 평가하였다. 임상기록과 수면다원검사를 포함한 모든 환자의 자료를 검토 및 분석하였다. 결 과: 총 86명의 환자 중 65명(75.6%)에게서 성공적인 결과를 얻었다. 경과관찰 기간 중에 28명의 환자에게서 경미한 전치부와 턱관절의 불편감이 보고되었으며, 특히 하악의 전방이동량에 따른 불편감은 7.0 mm 이상의 환자에게서 두드러지게 보고되었다. 하악의 전방이동량과 임상 결과와는 직접적인 관련은 없었다. 결 론: 중증도와 상관없이 하악전방이동장치는 폐쇄성 수면무호흡증 환자의 효과적인 치료방법의 하나로 선택될 수 있다. 잠재적인 치과적인 부작용을 방지하기 위하여 하악전방이동장치의 치료시에 하악의 전방이동량을 우선적으로 고려하여야 할 것이다. Objectives: The purposes of this study were to estimate the effect of mandibular advancement device (MAD) and to evaluate the influence of the advancement amount of mandible in the application of MAD for obstructive sleep apnea (OSA) patients. Methods: From the patients who were diagnosed as OSA by polysomnographic study at Seoul National University Bundang Hospital from January 2007 to February 2009, the patients who chose MAD as treatment option were included in this study. All the patients’ data including clinical records and polysomnographic studies (both pre- and post-treatment) were reviewed and analyzed. Results: Successful results were obtained in 65 patients of 86 patients (75.6%). In the follow-up period, mild discomfort of anterior teeth or temporomandibular joint (TMJ) were described in 28 patients, especially in the cases the amount of mandibular advancement were more than 7.0 mm. There was no direct relationship between the amount of mandibular advancement and clinical outcome. Conclusion: MAD was effective treatment option for the OSA patients regardless of severity. For the prevention of potential dental complications, the amount of mandibular advancement should be considered at the time of MAD treatment.

Purpose: The purpose of this study was to evaluate the histological healing process of 3 different types of xenogenic tooth bone graft material and xenogenic bone graft material. Methods: Three types of human tooth bone graft material (chips, crowns, and roots) and BioOss (Geistlich Pharma AG, Wolhausen, Switzerland) was filled at the preformed 4 round-shaped calvarial bone defects of beagle dogs. The beagles were sacrificed at 2, 4, 8, and 12 weeks, respectively, for radiological and histological evaluation. Results: Increased strength and radiopacity were detected in all graft material groups in time-dependent manner. New bone was formed and matured surrounding the graft material histologically. Also, a new bone was directly integrated with graft material. Conclusion: It was expected that newly developed tooth bone graft material would show good bone healing capacity if it was used as a graft material for the restoration of bony defect.

Objective : Trauma has been a controversial issue although it has been considered to be a major factor for the temporomandibular disorder(TMD). We evaluated the relationship between macrotrauma or microtrauma and TMD. Methods : This study was performed in patients with TMD undergoing treatment at SNUBH from October 2006 to January 2007. Sixty one male patients and 166 female patients(total 227) were included and the average age was 34 years(ranging from 14 to 85 years). We investigated the possible etiologic factors, diagnosis and treatment with the review of medical records and radiography. Chronic pain, depression, somatic score(including pain item), somatic score(excluding pain item) were evaluated on the basis of diagnostic index from the Research Diagnostic Criteria on TMD. Results : Eighteen patients(7.9%) out of 227 patients suffered from TMD as a result of macrotrauma. Ninety four(41.4%) patients had microtrauma and six patients(2.6%) had both macro- and microtrauma(etiologic factor). The main symptoms included pain. joint noise and mouth opening limitation while the other symptoms were headache and tinnitus. The patients had suffered from TMD for average 41 weeks (ranging from 1 to 480 weeks). 116 patients took splint as a major treatment. As a prognosis, 19 patients(8.4%) recovered completely. 26(11.0%) had improvement and 181(80%) had persistent symptoms. 1 patient(0.4%) underwent an arthroplasty. Diagnostic index from RDC chart showed that macrotrauma was the highest score(except depression score) among the other etiologic factors. Conclusion : This study showed that macro- and microtrauma can be considered to be the major etiologic factors of TMD, which also affect the chronic, depression and somatic discomfort.

Objectives : This study was carried out to research the protective effects of Sagunja-Tang(SA) through in vivo experiments, and tried to investigate the relation between oxidation of liver tissues and deficiency of Qi. Methods : Acute liver injury which initiated from free radical induced by $CCl_4$, were applied to mice and metabolic data were obtained. In order to measure the degree of liver injury, serum level of alanine aminotransferase(AST), aspartate aminotransferase(ALT), creatinine, blood urea nitrogen(BUN), total protein(TP) and glucose were measured. Lipid peroxidation of liver slice was examined by measuring malondialdehyde(MDA), a product of lipid peroxidation. Results : SA had protective effects on $CCl_4$ induced acute liver injury by decreasing serum level of ALT. Kidney injury was induced by injection of $CCl_4$ too, and SA protected kidney injury by decreasing serum level of creatinine and BUN. Conclusions : Through this study, we found that SA have healing effects on liver and kidney injury of $CCl_4$ induced oxidative stress that is similar to deficiency of Qi. And further studies have to be followed to certify the mechanisms.

Adequate bone quantity is one of the important factor to obtain osseointegration after implantation. Guided bone regeneration (GBR) has widely used in implantation for reconstruction of bony defects. Since introducing this procedure, there are many studies about survival rate of implants, changing in surrounding bone volume after function. The purpose of this study was to evaluate the amount of resorption according to placement timing and survival rate after function. The subjects were patients who had been operated with GBR from Jun 2003 to Jun 2004 in Seoul National University Bundang Hospital. They were divided into simultaneous and delayed placement group. The follow up had been performed at the time of just after GBR, 1, 3, 6, 12, 24-month later and standard periapical radiographs were taken to estimate the bone level at the time. The total average of bone level change in radiographs was 1.94mm(${\pm}0.25$), and 1.92mm(${\pm}0.72$) in simultaneous installation, 2.03mm(${\pm}0.25$) in delayed installation. In this report, the survival rates were 92.2% in simulataneous group and 92.3% in delayed group. Insufficient primary stability, early contamination of wound, overloading, poor oral hygiene, and infection were thought to be associated factors in the failed cases.

Inselecting scars for treatment, attention be paid not only to the features of the defect as seen objectively but also to the element of the defect most disturbing to the patient. We revised the scar tissues with simple elliptical excision, Z-plasty, modified Z-plasty, W-plasty and hand dermabrasion in varialbe pattern of scars and got the favorable results. The success rate of scar revision usually depends on the patient's subjective judgement. We must inform our patient the limitation of scar revision and importance of postoperative care. The oral and maxillofacial surgeons must resolve the variable scars which re involved in variable operations and traumas.

Promoting policy to involve plant EPC companies for package deal has been studied to acquire overseas energy resources. The effectiveness of the package deal with the plant EPC companies has not been successful because the participation of the plant EPC companies is very rare. It is difficult for the plant EPC companies to join the package deal due to the lack of the fully responsible organization to support the plant EPC companies participating in a package deal. The followings are suggested as the ways to promote the participation of the plant EPC companies for package deal in this study; 1) financial support of the government for plant EPC companies 2) political support of the government for plant EPC companies 3) specialization of the advanced countries for public-private cooperation.

Angiolymphoid hyperplasia with eosinophilia is an unusual and controversial lesion that occurs primarily in the head and neck area. This lesion was usually confused with Kimura's disease. We present the case of a 32-year-old woman with massive soft movable mass in left facial area which was diagnosed preoperatively as a fasciitis nodular. The final histologic diagnosis of the excised mass was angiolymphoid hyperplasia with eosinophilia(ALHE). 호산구 증가증을 동반한 ANGIOLYMPHOID HYPERPLASIA는 주로 두경부의 표층에 발생되고 진단에 어려움이 있는 특이한 질환이다. 일본에서 처음 보고된 이래 주로 동양에서 종종 보고되어온 KIMUR'S DISEASE와 많은 논란이 되고 있다. 저자등은 좌측 안면부에 거대한 유동성의 종괴를 주소로 환자로서 술전 진단에 상당한 어려움이 있었고 술후 최종적으로 ALHE로 진단된 32세 여자환자를 문헌고찰과 더불어 보고하는 바이다.
